Here's my two-cents:
How would you react if the video showed a JW "speaking out" in churcg during the funeral of Senator John McCain?
I think you'd agree it would have been outrageous.
What is outrage for the goose is outrage for the gander.
I think I understand the personal pain that might drive a person to do this, but I doubt that it accomplishes anything other than reinforcing the notion among the JWs that they are being "persecuted" because they are "True Christians."
Don't do this.
